Abstract of the Disclosure The present invention provides borated reaction products made by (a) reacting an alkenylsuccinic compound with an arylamine of the formula ArNHAr1 wherein Ar and Ar1 are aromatic groups having from 6 to about 50 carbon atoms, which may be the same or different and wherein Ar and Ar1 may each be independently substituted with a C1- C4 aliphatic group, followed by (b) reacting the product of (a) with an alkanolamine of the formula (HOR3) x N(H)y wherein R3 is an alkylene group having from 1 to about 6 carbon atoms, x is an integer of 1 to 3 and y is 0 to about 2, their sum being 3; and (c) thereafter reacting the product of (b) with boric acid or a compound of the formula (RO)p (BO)q ZrY wherein R, Y and Z are hydrogen or an alkyl group of from 1 to about 6 carbon atoms, p and x are 0 to 2, and q is 1 to 3. These borated reaction products are highly effective dispersant and antioxidant/anticorrosion additives for lubricant compositions.
